This presentation covers techniques to create and implement a 'datawindow enhancement service' within an existing PowerBuilder application with the goal of providing improved functionality while keeping disruption to application users to a minimum. It is similar to the session presented at the 2012 PowerBuilder Developers Conference held in October in conjunction with SAP TechEd. Focus for this session will be on the creation of the service object, implementing example functionality enhancements with existing datawindows, and ideas for further expansion of the service.
